python-ldap provides an object-oriented API to access LDAP directory servers from Python programs. Mainly, it wraps the OpenLDAP 2.3+ libs for that purpose. Additionally, the package contains modules for other LDAP-related stuff (such as processing LDIF, LDAPURLs, and LDAPv3 schema).
LDAP Account Manager (LAM) is a web frontend for managing entries (e.g. users, groups, DHCP settings) stored in an LDAP directory. LAM was designed to make LDAP management as easy as possible for the user. It abstracts from the technical details of LDAP and allows persons without technical background to manage LDAP entries. If needed, power users may still directly edit LDAP entries via the integrated LDAP browser.
Simple Groupware is a complete enterprise application offering email, calendaring, contacts, tasks, document management, synchronization with cell phones and Outlook, full-text search, and much more. Simple Groupware combines standards like RSS, iCalendar, vCard, IMAP, POP3, SMTP, CIFS, CSV, WebDAV, LDAP, and SyncML under one platform. Unlike other groupware software, Simple Groupware contains the programming language sgsML to enable the quick customization and creation of powerful Web applications.
dFlex is a meta-directory application: a set of applications to be used for LDAP directory replication and directory data mapping and translation. It is designed as a simple and flexible framework to provide heterogenous directory data synchronization. It was originally written for a specific directory environment, and preconfigured for common tasks of replication in that environment. However, it can be easily configured to match replication, synchronization, and data mapping needs of a wide variety of directory systems and configurations.
389 Directory Server (formerly Fedora Directory Server) is a full-featured LDAPv3 compliant server. In addition to the standard LDAPv3 operations, it supports multi-master replication, fully online configuration and administration, chaining, virtual attributes, access control directives in the data, Virtual List View, server-side sorting, SASL, TLS/SSL, and many other features. The transactional Berkeley DB 4.2 is used as its data store and a full plug-in API allows developers to extend the the functionality of the server in many ways, and many of the core features of the server are already implemented using this API. The server is very mature, having started out as Netscape Directory Server.
PALDAP is yet another LDAP administration tool which includes a complete PHP LDAP API. It features an advanced LDAP schema parser. It is designed to be comfortable for experienced LDAP administrators, but it is also made so that LDAP administrators can configure it in such a way that it will be easy enough for their users to use.
Kolab is a groupware system that provides a comprehensive and flexible solution for workgroups. Email, contacts, and group calendars can be managed via the Web, Windows/Outlook, and Linux/KDE. It supports offline synchronization and full seamless support of mixed client environments because the Kolab-XML storage format is fully open and avoids MAPI/TNEF.
ldapuseradd is a set of utilities that aid in the management and deployment of user accounts with support for plugins to manage requirements. The LDAP user management toolset uses a highly configurable user group profile system to distinguish targeted services. It is like an LDAP-based useradd/mod/del drop-in replacement with modular features. It scales well from small businesses to ISPs, hosting providers, and universities.
